so I typed in 4-6mm hex bolts in search thinking I could replace out the Honda Rebel bolts I had stripped trying to pop them free from a new Motorcycle I purchased. I get these dinky toothpick size bolts. they all have the same size nuts they're just longer. they're 4-6 in mm length not head size?I let them sit until I could get my bike in. I didn't even unwrap the bag it came in until an hour ago (which is about 3 weeks after receiving it). Not sure what I can use these for but they're not going to work on my bike. Pretty bummed out but I'll just hold onto them. Maybe I can use them in a hobby of some sort

This is how it came. If you love sorting through screws then this is an excellent option! As far as hardware seems alright.

Being a hobbiest with 3d printers and small electronics, I go through M3s like they're nothing. Getting a set with both the strength of a socket cap and the low profile and sleeker looking button heads is nice combination. I love that it comes with long 35mm screws, since that's something most kits don't come with.If I were to have a complaint, its the box they come in. No one likes these things, they're fragile and the dividers are always sliding enough to send screws into the wrong compartment. They're cheap and ubiquitous so I suppose I cant expect anything better, but at least a dab of hot glue fixes the dividers coming loose all the time

This 2135-piece M3 screw assortment kit is a great value for the price. It's got pretty much every M3 screw you could need for 3D printing projects, which is exactly what I use it for. The variety of lengths and head types (button and socket head) is excellent. The 10.9 and 12.9 grade alloy steel seems decent enough; they haven't stripped or broken on me yet. My only real gripe, and it's a minor one, is that the screws were all jumbled together in the case when it arrived. It was a bit of a pain to sort them all out again, which is definitely something the seller could improve. However, considering the sheer number of screws and the price, I can't complain too much. Once I got them organized, it's been incredibly convenient having such a comprehensive set on hand. If you're a 3D printing enthusiast, or just need a good selection of M3 screws, this kit is a good option, just be prepared to do a little sorting when it arrives.

This is a great pickup for anyone working on 3d printers. M3 is a really common size and is easy to implement into your own designs or use for repairing or modding your 3d printers.

Kit came exactly as described. All the dividers in the clear case were secure, and all of the screws, washers, and bolts were included. Counted each size, and all of them were included the case.Quality of the screw threads are great. These mixed in well with the other screw I have for small projects. Great value for the money.

I can only assume i got the right amount of each… 75% of the dividers were sitting on top and all of the screws were mixed together.. Ill still make use of it all but going to be a pain to sort

Poor quality, the organizer is cheaply made and the screws get mixed up.
